Copper is the traditional material for timpani and lends itself well to the pitch range of the drum while being moldable to achieve different tonal characteristics. Hammering the copper has the same effect on resonance and sustain as it does on bronze cymbals by allowing the material to vibrate more freely.
Fiberglass is a hard, reflective material that is easily shaped into a bowl with a more narrow pitch response and a shorter sustain than copper. Fiberglass is cheaper overall and is a good choice for intermediate schools, smaller churches, and theaters
